Identify the charges of the subatomic particles involved: protons have a charge of +1 each, and electrons have a charge of -1 each.
Calculate the total positive charge by multiplying the number of protons by their charge: \(9 \times (+1) = +9\).
Calculate the total negative charge by multiplying the number of electrons by their charge: \(10 \times (-1) = -10\).
Find the net charge of the ion by adding the total positive and total negative charges: \(+9 + (-10) = -1\).
Interpret the result: since the net charge is -1, the ion has an overall charge of -1.
